Shark attacks might be slightly sensationalized by the media, but the cold-blooded beasts really do present a significant risk to surfers. Sharks don't necessarily want to chomp down on a salty grommet, but with their wetsuits and silhouette on the water, surfers really do resemble a tasty seal meal. The rise in attacks over the last couple of years, particularly in Australia and South Africa, pretty much prove it. They're not vicious, just hungry.
Even so, it's hard to imagine knowing a 10-foot shark is in the water and still choosing to go out to chase the waves. Because that's exactly what this guy was doing. He knew the shark was there, and he decided to surf up for a closer look. It sounds like a completely stupid idea, but somehow the surfer escaped with his life.
